Abstract
The authors report an analysis of 47 leukemia patients (including 9 from our own medical center) whose courses were complicated by 48 episodes of clostridial septicemia. There were 36 adults and 11 children; acute myelogenous leukemia and acute lymphoblastic leukemia accounted for 61.7% and 14.9% of cases, respectively. All patients for whom remission status was known were in leukemic relapse. Fever was a presenting complaint in at least 36 patients whereas neutropenia, thrombocytopenia, and gastrointestinal lesions were noted in 100%, 90.9%, and 87.9%, respectively, of the patients for whom information on these parameters was available. Overall mortality from clostridial septicemia was 78%; none of the children and none of the patients with intravascular hemolysis survived. Overall, antibiotic therapy resulted in a 40% survival rate. However, among patients receiving beta lactam and/or chloramphenicol therapy, 57% survived their episode of clostridial septicemia. Prompt initiation of appropriate antimicrobial therapy offers the best chance of survival in leukemia patients with clostridial septicemia.
